BARREL-FORMING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 238,743, dated March 8, 1881.

Application filed June 24, 1880. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL WRIGHT, of the town of Harriston, in the county of VVellington, in the province of Ontario, Canada, have invented a new and useful barrel-forming machine, of which the following is a specification.

My invention relates to that class of machines for forming double-skin bulge-barrels, in which a collapsible forming-drum is employed; and it consists in certain improvements therein, as hereinafter more fully set forth.

In the accompanying drawings, Figure l is a longitudinal section of a machine embodying my improvements. Fig. 2 is a plan of the same, and Fig. 3 a cross-section. Fig. 4 is a detail of cylinder form.

A is a cylindrical form or shape, constructed in four (more or less) sections, A, supported by hinged standards 13 from a shaft, O, in such manner that they are capable of being drawn inward toward a common center in pairs, so as to reduce the diameter of the form to the necessary extent required for the removal of a completed barrel. The movement of the sections is accomplished by means of a lever, D, which is pivoted to the frame of machine, and is connected to a sleeve, E, to which sleeve the sections of the form are coupled by the bars F in such manner that, as the sleeve is moved backward or forward, a corresponding inward and outward movement is communicated to the sections of the form. The manner of connection of the bars F to the sections of the form is such that the sections work in pairs, two opposite sections being moved slightly inward before the remaining two sections are moved. The result of this arrangement is that the two sections moved last overlap the other sections, and that all the sections move inward and outward without interfering with each other.

As shown in drawings, the form is mounted upon a frame of suitable construction. The form may be arranged to be driven by gearing or hand to feed the staves in between the roller G, retaining-bars H, and the face of the form. One section, B, of the retaining-bars, is hinged to the frame, as seen at a, Fig. 2, by hooks and staples, or in any other suitable manner, so

that the section H may be folded down when it is desired to remove the barrel, and the hinged section may be retained in an upright position, in the process of forming the barrel, by a removable transverse bar secured to the frame and bearing against the retaining-bars, or any other suitable means may be employed for the purpose. The other section, H, of the retaining bars is fixed in the frame of the machine.

In the manufacture of the barrel the staves are first jointed in a stave-jointing machine to give the barrel the proper amount of enlargement in the center. The staves are then placed in succession upon the expanded form and fed in by the spiked roller G between the surface of the form and the face of the retaining-bars H in two layers, with the joints of the staves overlapping or breaking with each other. The staves are fed and pressed into place by a rotary movement of the form, communicated by v suitable gearing or by the hand or foot of the operator, until the whole surface of the form is covered with two thicknesses of staves. Prepared hoops are then driven over the staves at each end of the form, to secure them from displacement, and nailed to the staves, the points of the nails clinching on themetal form. The irregular ends of the staves are then cut by means of a pair of gaged saws, I, which are pulled forward into position as the form is rotated. As a modification, these saws could be supported in a position where they would cut the staves, as the form was rotated in feedingin the staves. The barrel is then removed by folding back the section H of the retainin g-bars, collapsin gthe form, and removing the shaft 0 from its outer bearing in the frame, or removing that part of the frame carrying the end bearing of the shaft, after which the barrel is completed by hand by the addition of the remaining hoops and heads.

I claim as my invention, and desire to secure by Letters Patent 1. The combination,with the barrel-form A, constructed in sections, substantially as described, of the hinged standards B, shaft 0, sleeve E, bars F, constructed to move the sections of the form successively, and lever D, substantially as shown and described.

2. The combination, with the barrel-form A,

constructed in sections, substantially as described, of the hinged standards B, shaft (3, sleeve E, bars F, constructed to move the sections of the form successively, lever D, retaining-bars H, and hinged section H, substantially as described. V

3. The combination, with the barrel-form A, constructed in sections, substantially as described, of the hinged standards 13, shaft 0,

sleeve E, bars F, constructed to move the sec- 10 tions of the form successively, lever D, fixed retaining-bars H, hinged retaining-bar section H, and saws I, substantially as described, and for the purpose set forth.
